TJ7533GF from HTC Korea TAEJIN Tech, in a SOT-89-3. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Ground pin for the regulator, shared by the TO-92 and SOT-89-3L packages. |
| 2 | VIN | power_in | Input voltage pin; the recommended operating input range is 2.7V to 20V and the absolute maximum input supply voltage is 28V. |
| 3 | VOUT | power_out | Regulated output voltage pin (3.3V for TJ7533GF), supplying up to 250mA of load current. |
